nasty rattle, no obvious source. No check engine light on.
Noise from motor, timing chains and guides were bad
Does my vehicle have timing chain or belt
A piece of the timing chain cover came up through the valve cover. Truck was still running!!
I started it up and it ran for about ten min and then I went to put ot in drive and the engine shut off . I started it back then that's when I heard it clanking or banging of something under the hood up at the front of the motor.
timing chain broke causing metal to enter motor. motor blown
Went through total of 3. yes 3. 2006 it caused a valve to set on top of piston. Got a rebuilt motor it ran 1 year. the only way shop would cover said problem, under warranty. was put on(all) mufflers. 3 catalytic mufflers, do to possible back pressure problems.so here I am with a great truck with bad engineers or money grabbing (?). So next, I hope that show will come that fixes problems with one loved truck. Put a mustang motor, trans & ecu. make my wife her ford adrenaline 2002. Problem FREE
